Title: Subscriber line monitoring system in electronic telephone exchange - compares transmitted and reflected test signals to determine state of line
Inventor: LECHNER ROBERT DIPL ING
IPC: H04M3/30
Filed: 1979-09-20
Abstract: A test signal generator (G) is connected via the exchange four wire selector circuit system (TSI) to the transducer (GA) in the subscriber line terminal equipment (TS). The generator feeds signals into the transmit channel. Reflected signals are passed from the transducer via the receive channel to an evaluating circuit (A) together with a suitably time delayed output direct from the generator. The evaluation circuit constructs a transfer function from the two signals received from which the characteristic curve for the subscriber line is determined. If this curve departs from an established norm a fault is recognised and signalled. A computer (R) carries out the evaluation of the transfer function. If the system operates with digital signals then the test signal generator output passes first through an analog to digital converter (A/D) before connection to the exchange equipment.

Title: Hot water injection and vaporisation engine - has jet(s) spraying hot water into preheated space between piston and cylinder head
Inventor: LANGMAIER JOSEF
IPC: F01K21/02
Filed: 1980-02-14
Abstract: The two-stroke engine generates the necessary evaporation heat by compression of the drawn-in air. The compressed and therefore heated air is conducted by opening of a valve. The removal of the compressed air leaves a pressure-free, hot space between the piston and the cylinder head. Hot water is sprayed into this space so that the vaporisation follows immediately. One or more adjustable injection jets are mounted in the cylinder head. The vapour heated by the injected water and the remaining vapour are condensed. The water resulting from the condensation is filtered and returned to the main tank via an auxiliary tank. The engine is initially heated for working by a heating arrangement but is then kept in operation by the compression heat.
